With density problems we can convert mass to volume or volume to mass, which is a new trick. The density of a substance gives us a way to make that conversion. For example, gold’s density is 19.3 grams per mL. If starting with milliliters, we use 19.3g/mL to convert to grams. If starting with grams, we use 1 mL/19.3g to convert to milliliters.

Thus the molar mass of magnesium is 24.3050 g/mol, compared to carbon’s molar mass of 12.011 g/mol. The number of grams in the molar mass of an element is the same as the atomic mass. Translating atomic masses into molar masses, you can construct conversion factors that convert between the mass of an element and the number of moles of the.

A gram per litre or gram per liter (g/L or g/l) is a unit of measurement of mass concentration that shows how many grams of a certain substance are present in one litre of a (usually liquid or gaseous) mixture. It is not an SI unit – the SI unit of mass concentration is kilogram per cubic metre, which is equivalent. Metric prefixes are often applied, giving units like milligrams per litre.

and one liter is the best assumption for this problem. Step 2. Find the total mass of the solution. Multiply 1 L X the density (1.84 g/mL) X 1000 mL/L. This gives 1840 grams of solution. Step 3. Calculate the grams of the solute. 18M means 18 moles of sulfuric acid per one liter of solution. Convert 18 moles to grams.
